Patent CA-2025951-C (CA)
Inventor: MCCANDLESS JAMES C
IPC: F02D9/04
Filed: 1990-09-21
Granted: 1999-11-30
Abstract: An exhaust back pressure control system includes a valve in the exhaust outlet of a turbocharger of an internal combustion engine which is controlled by an engine control microcomputer. When the valve is moved toward a closed position, it restricts the exhaust flow, thereby increasing back pressure and friction within the engine by producing an artificial load thereon, and thus speeds up the warming process taking place within the engine upon starting thereof. The valve is moved by an actuating piston within a hydraulic cylinder using engine oil pressure controlled by an electrically operated valve receiving a pulse width modulated operating signal from the engine microcomputer, the operating signal being generated to provide a desired back pressure as a function of engine coolant temperature, engine speed, engine fuel consumption, and actual back pressure. Operation of the system is enabled if the ambient air temperature is below 2°C and also for the period that the elapsed time since start of engine is less than thirty seconds, the latter enablement being provided to exercise the system during extended periods of warm weather operation when the system would otherwise be inactive.

Title: Context-dependent speech recognizer using estimated next word context
Inventor: BAHL LALIT R
IPC: G10L15/32
Filed: 1993-02-18
Granted: 1996-12-10
Abstract: A speech recognition apparatus and method estimates the next word context for each current candidate word in a speech hypothesis.  An initial model of each speech hypothesis comprises a model of a partial hypothesis of zero or more words followed by a model of a candidate word.  An initial hypothesis score for each speech hypothesis comprises an estimate of the closeness of a match between the initial model of the speech hypothesis and a sequence of coded representations of the utterance.  The speech hypotheses having the best initial hypothesis scores form an initial subset.  For each speech hypothesis in the initial subset, the word which is most likely to follow the speech hypothesis is estimated.  A revised model of each speech hypothesis in the initial subset comprises a model of the partial hypothesis followed by a revised model of the candidate word.  The revised candidate word model is dependent at least on the word which is estimated to be most likely to follow the speech hypothesis.  A revised hypothesis score for each speech hypothesis in the initial subset comprises an estimate of the closeness of a match between the revised model of the speech hypothesis and the sequence of coded representations of the utterance.  The speech hypotheses from the initial subset which have the best revised match scores are stored as a reduced subset.  At least one word of one or more of the speech hypotheses in the reduced subset is output as a speech recognition result.

Abstract: An encoding method for digital image data comprising consecutive blocks of data groups having as content binary values always of an equal number of pixels of an image, utilizing a code which indicates that the encoded block is partly equal to the corresponding part of a reference block, the reference block preferably being the preceding block, and identifies the end point of that part of the reference block by reference to transitions in pixel value in the reference block. On decoding, that part of the reference block is taken over in the decoded block.      This encoding method is, in practice, combined with run length encoding and encoding by copying an entire data group in the code.

Abstract: A method of saturating and humidifying the incoming flue gas of a flue gas desulfurization process without the need for underspray headers or the like. Initial humidification occurs by passing the incoming flue gas through a continuous liquid curtain of recycled bottoms product falling from an awning over the flue gas inlet. Further saturation and humidification occurs by causing recycled bottoms product to fall or rain from an overhead tray or grid onto the flue gas prior to passing through the tray or grid. In order to accomplish such humidification, there is an unobstructed passageway between the flue gas inlet and the lowermost tray or grid.

Abstract: A system and method of rendering a curve using data look-up tables for rasterizing the curve. The curve is subdivided so that it is approximated by a series of straight line segments of approximately equal length, with no line segment exceeds two pixels in length. The system subdivides any line segment that crosses horizontal axis of two adjacent horizontal scan rows. If the line segment does not cross the horizontal axis of a scan row, the pixel does not require detailed analysis. If the line segment does cross the horizontal axis of a particular horizontal scan row, the system uses look-up tables to determine the distance from the center point of the pixel in winch the line segment crosses the horizontal axis to the point at which the line segment crosses the horizontal axis. The system uses three indices as pointers to the data look-up table containing the desired data. The three indices are themselves pointers to separate index tables in which the multiplication calculations required for the data look-up table have been precalculated and are incorporated into the values stored in the index tables. The index tables also incorporate a reduction in resolution from 1/64 to 1/8 pixel resolution. The index tables are also nonlinear to allow more data entries in areas where the round off error resulting from the resolution reduction are greatest. If the line segment crosses the horizontal axis to the left of the center of a pixel, the logic state for the pixel is changed. The system can be implemented on any computer and operates with any raster scan graphics display unit.
